GATE.

Application filed December 30, 1919.

T 0 (all whom it may concern:

Be it known that we, FREDERICK WV. EWALD, a resident of Brooklyn, county of kings, and State of New York, and Han- BERT G. THOMSON, a resident of the city and county of New York, in said State, both citizens of the United States, have invented certain new and useful Improvements in Gates, of which the following is a specification.

This invention relates to gates, having reference more especially to that class of gates in which heavy wire fabric is supported under tension by and within a rectangular frame structure of metal work.

The object of our invention is to provide a simple and inexpensive brace which can be applied with facility to the frame structure and which brace can be readily adj ustcd diagonally of the structure to exert a substantial and rigid bracing action upon the latter.

.Vith this object in view our invention comprises certain novel features of construction and combinationsof parts which will be hereinafter described and claimed.

In the drawings- Figure 1 is a front elevation of a single swinging gate embodying our invention.

Fig. 2 is a sectional detail, enlarged, of the upper hinged corner of the gate, showing an adjustable hook bolt for a diagonal brace rod.

Fig. 3 is a horizontal section, as on the line 3-3 of Fig. 2.

Fig. 4. is a horizontal section through the lower free corner of the gate frame and adjuncts, as on the line 4- 1 of Fig. 1.

Fig. 5 is an elevation of the upper free corner of the gate frame, showing the adjacent locking devices.

Fig. 6 is a horizontal section, on a larger scale, as on file line 6-6 of Fig. 5.

Fig. 7 is" n elevation of a double swinging gate embodying the invention.

Referring to the drawings, 10 designates the upper and lower rails of a gate frame; 11, 12 the respective verticalend members thereof, and 13 interlcoped or interwoven open wire fabric secured to and held under tension betweenthe respective end members. Each rail 10 comprises a stout metal tube, and each end member, (11, 12), comprises two channel bars arranged back to backin spaced relation to each-other and connected at intervals by means of transverse bolts 14. At the respective corners of the frame are Specification of Letters Patent.

pairs ofhorizontal channel cheek members 15 the flanges of which are welded to the contiguous flanges of the proximate end bars to constitute, in effect, integral parts f the latter. Thesemembers embrace the ends of the respective rails and are bolted thereto to effect a firm and rigid union of the rails and end bars. The cheek members at one end of the frame are constructed to i receive and rigidly supportthe tongue-like bodies 16 of hinge connections 17, all. as set forth in Letters Patent of the United States No. 1,273,359, dated October 29, 1918. In the present construction the body, preferably hollow, of the upper hinge connection is provided with diagonal perforations 18 in line with each other and with thelower corner of the opposite or free end of the frame, which perforations slidingly receive the shank 19 of an adjustable hook-bolt 20. The outer end of the shank is screw-threaded, as at 21, and is provided with an adjusting nut 22 which bears against the outer, preferably flattened, corner of the hinge body. Engaged with the hook 20 is thebent end. portion 23 of a brace rod 24 which extends diagonally towardand is fastened to the lower corner of the gate frame adjacent to the bars 12. The brace rod illustrated is of elongated loop form, its upper or curved end being engaged with the hook 20 at the upper corner of the end bars 11, and the free extremities of its parallel limbs being hook-shaped, as at 25, and engaged with the open end of the lower rail 10 adjacent the ends bars 12 of the frame; said limbs embracing and laterally supporting the wire fabric. Thus the lower end of the brace rod is securely yet dctachably connected to the frame structure, and when the hook-bolt 20 is adjusted by manipulation of the nut 22, the said rod is brought and heldunder tension to exert a substantial and rigid bracing action on the structure. The diagonal brace may comprise a straight rod having one end bent to form a hook for engagement with the hook-bolt 20 .and having its opposite cnd properly formed for connection with the frame structure. In connection with our improved gate structure abovedcscribed, locking mechanism therefor of the following construction may be employed. Fitted in and secured to the channels of the respective cheek members 15 of the end bars 12 are the limbs of two guide brackets 28 for a vertically movable locking bar 29 which is adapted to be moved into and out of registry with a suitably-disposed basal socketed keeper 30 when the gate is in closed position. Preferably each of these brackets comprises a strap of wrought iron bent to form a rectangular guide opening and spaced parallel tongues 31 which are shaped to fit snugly into the channeled ends of the adj acent pair of cheeks. The tongues are held securely in place by a cross-bolt 32 which passes through the same and the contiguous cheek members. The locking bar .49 is provided adjacent its upper end with two spaced apart collars 33, 34, the upper one (33) of which is so disposed as to bear upon the upper guide bracket when the said bar is in its down or looking position; and the lower col lar 34: is positioned to contact with the bracket and limit the upward movement of the locking bar when the latter is raised from the keeper. The frame bars 12 are provided with rip-projecting portions to which are pivoted the ends of a loop-like hasp 35 adapted to be swung upon and from an adjacent supporting element, as the stationary gate post 36, having an up-standing eye extension 37 which may be an integral or a separate partof the post, as desired. The construction and arrangement of the parts just described are such that when the locking bar is in its down position inlocking engagement with the keeper, the hasp can be swung over upon the post in a manner to embrace the up- .per end of the locking bar and also the eye extension, the limbs of the hasp thus bearing upon the upper collar 33. Thereupon if a suitable key lock, such as the padlock 38, be applied to the eye extension of the post the hasp will be effectually locked in place, thereby securely'locking the bar 29 in engagement with the keeper and effectually locking the gate in closed position. When the padlock is removed, the hasp can be readily swung back to release the locking bar, as indicated by the dotted lines in Fig. 5,

which bar can then be manually raised from the keeper to unlock the gate.

In order to maintain the locking bar temporarily in raised position, as occasion may require, a gravity clamp 39 for co-action with the locking bar is pivoted between the limbs of the upper guide bracket; the ad acent cross-bolt 32 for the bracket affording a convenient pivot support for the clamp. This clamp, in its preferred form, comprises a vertically-disposed body having at its upper end, in a plane above the axis of .the body, an outwardly projecting nose 40 constituting a clamping portion which normally gravita'tes against the adjacent side of the locking bar, and having also a depending tail piece 41 which constitutes a convenient thumb piece to facilitate the movement of the clamp from the rod. The arrangement of the clamp nose in relation to the axis of the clamp is such that in the act of raising the locking-bar, said bar slides freely against and past the clamp nose, but when the bar is released said nose is depressed by the frictional contact of the descending bar thereagainst, thus firmly gripping the bar and holding it in raised position. By properly pressing the tail piece the clamp is moved to release the locking bar and permit it to drop into locking engagement with the socketed keeper.

In Fig. 7 our invention is illustrated as applied to a double swinging gate wherein each of the frame structures is provided with a diagonal brace construction similar to the single gate above described, and in which double gate the eye device is formed and positioned on the end bars 12 of the additional frame structure so as to receive the pivoted hasp 35 when the latter is swung over to lock the locking bar 29 in engagement with the keeper. 7

We do not limit ourselves to the specific details of construction herein disclosed as the same may be modified within the principle of our invention and the scope of the appended claims.
